Pulling an Agent

The act of accidentally deleting or overwriting any 100% complete game save from any video game requiring one. This has originated when some poor soul just recently completed the video game Grand Theft Auto IV to 100% and immediately overwritten it with a beginning save game.

Example of "Pulling an Agent":

A: "Hey dude, I just beat GTA IV!"

B: "Sweet! Hey, I just figured out if you save your game on the first mission it'll say an error when you re-load it!"

A: "Really? let me try!"

A: "FUUUUUUUUU! I just saved over my complete save game!"

B: "Dude, you just pulled an Agent."

A: "FML."
